Title : On farm experiments on fingermillet: participatory variety selection (PVS), diversity block (DB) and community based seed production (CBSP) Material Type: printed text Authors: Sanjaya Gyawali ; Bharat Bhandari, Author ; Khem Choin, Author ; Upreti, R.P., Author Publication Date: 2005 Pagination: 55-69 p. Languages : English (eng) Keywords: Diversity block, Finger millet, Landrace. Participatory variety selection, On-farm experiments Abstract: Participatory variety selection (PVS), diversity block (DB) and Community based seedProduction (CBSP) are used as participatory approaches of experimenting with landraces /varietal options in on-farm. We found these approaches less adopted in neglected but nutritiousfood crops such as finger millet. In this paper we describe various participatory approaches ofon-farm experimentation and scaling up of farmers preferred landraces and/or varieties. We useddiversity block as an entry point to understand farmers preferred traits, enhance farmers' participation in on-farm trials and blend farmers' knowledge in landrace enhancement and seedproduction activities. Participatory variety selection identified farmers preferred varieties GPU-25, ACC523-1 and Okhle-1 in Kaski districts. Community based seed production was adopted tomultiply seed of these varieties and linked to District Agricultural Development Offices to scaleup farmers preferred varieties in the region. We have described the landrace enhancement ofKalo Dalle and Samdhi Kodo.

Title : Planting Materials Seed Systems of Finger Millet, Rice and Taro in Jumla, Kaski and Bara Districts of Nepal Bimal Material Type: printed text Authors: Baniya, B.K., Author ; ,Tiwari, R.K., Author ; Chaudhary, Pashupati, Author ; Shrestha, Surendra K., Author Publication Date: 2005 Article on page: 39-48 p Languages : English (eng) Keywords: Seed flow, seed production, selection, storage, system Abstract: Formal and informal seed supply systems of rice (Jumla, Bara and Kaski), finger millet and taro
(Kaski) were studied in three ecosites of Nepal during 1999-2001 to understand the processes of
seed flow, seed production, seed selection and storage systems. A survey was conducted at 48 to
96 households. Informal seed supply was the only system in Jumla and Kaski and formal system
existed only in Bara. The main sources of seed were farmer’s own saved seed (67-91%), seed
from neighbors and relatives. Exchange of germplasm was the main basis of fulfillment from other
sources. All farmers obtained seed from their own village, while farmers introduced
materials occasionally from outside village. Most of the farmers followed seed selection before
or after crop harvest. Rice field selection and plant selection based on a fixed set of criteria
was the common practice. Non lodged plants with more grain per panicle, bold grains, well-matured
and uniform plants, long panicle, true to type, good looking grains, free from diseases and insects
were the main rice seed selection criteria. All farmers from both sites stored rice seeds by local
methods in the locally available containers. Mor and Mudkothi are the special straw containers to
store rice seed in Bara. Dhara is a special mud structure used to store rice seeds in Jumla. Finger
millet seed supply system was mostly similar to that of rice seed system. Ninety one percent
farmers saved seed for their own use; however, many of them changed finger millet seeds lots or
varieties regularly for their particular plot. Ears selection during harvest by set criteria for
seed purpose was the common practice. Farmers stored finger millet seed carefully in small locally
available containers and tried their best to maintain the quality of seed during different stage of
seed production. Taro has diverse planting materials: cormels, corms with eyes, suckers and corm
with small cormels. Taro planting materials management is totally informal and almost 89% farmers
saved these materials for their use and replaced them mostly after 3 years. Farmers had fixed
criteria of corms and cormels selection for planting purpose and focus and more on disease
free. Storage of planting materials was locally by using local materials and methods.

Title : Wheat varietal improvement for irrigated condition of mid hills of Nepal Material Type: printed text Authors: Thapa D.B, Author ; A Mudwari, Author Pagination: 178-193 p. Languages : English (eng) Keywords: Hybridization, Selection, Genotype, Rust, Grain Yield Abstract: During 2007/08 to 2009/ 10, hybridization, different generation nurseries, advanced lines (National and International), observation nurseries and different national and international yield trials under irrigated condition were the breeding activities of ABD, Khumaltar. Targeting the high yield and economical values, resistance to rusts, efficient nutrient use, good bread making quality and wide adaptive, different number of crossings were made. Superior genotypes were selected from the different generations by applying selected bulk method in early generations and single plant selection method at F5-F6 for generation advance suitable for irrigated condition of hilly areas. Prolonged drought season was occurred during 2008/09 season which adversely affected on data generation of yield trials and observation nurseries and also off spring generation..................

Title : Effect of Organic Sources of Nutrients and Plant Protection on Productivity of Orthodox Tea (Camelia Sinensis Kuntz.) Material Type: printed text Authors: Subba, N., Author ; NP Adhikari, Author ; Ghimire, K., Author ; ASR Bajracharya, Author Pagination: 78-85 p. Languages : English (eng) Keywords: Gumli Selection, mineral oil, enanthole, azatobacter incorporated fertilizer Abstract: The growing demand of quality organic tea with increase in awareness on the deleterious effect of
chemicals and its residue in human health has revived the need of organic tea management. Field
experiments were conducted in 2006/2007 to 200712008 in flam and Dhankuta districts to study the
effect of di.fferent organic sources of nutrients and pest management on Orthodox tea cv. Gumti
Selection. In addition to productivity, the effect of nutrients on green leaf production trend,
plucking intervals in di.fferent months and changes in composition of soil in the experimental plots
were also studied Four di.fferent organic sources of nutrients; vermi compost, azatobacter
incorporated commercial organic fertilizer, improved ditch compost with EM. traditionally made
compost and di.fferent organic plant protection methods; enanthole, parasitic fungi Trichoderma
viride, mineral oil for management of blister blight disease and locally made botanical pesticide,
mineral oil and ultineem for management of thrips were tested separately in a Randomized
Complete Block Design (RCBD) with seven replications. The effect of different organic sources of
nutrients was found significant on green tea leaf production. In both districts, highest production of
green tea leaves was recorded in plots with azatobacter incorporated fertilizer and least informers'
traditional compost in both years. The result showed green leaf production of 3125 and 3031
kg/hac in 12-15 year old plantation and 1822 and 1798 kg/hac in 8-10 year old plantation with
yearly application of 495 gmlbush of azotobacter incorporated fertilizer. Di.fferent organic
treatments did not di.ffer significantly in the severity of blister blight disease. However, lowest
infestation was observed in plots with Trichoderma application. Leaf damage percentage was found
significantly lower in treatments other than control in both districts. The effect of organic thrips
management was significantly di.fferent in green tea leaf yield. Non significant changes in soil
chemical properties due to organic nutrients were found among the treatments. However, small
incremttnl in nitrogen and potassium contenl over the time was observed.Link for e-copy: http://elibrary.narc.gov.np/?r=1642 Effect of Organic Sources of Nutrients and Plant Protection on Productivity of Orthodox Tea (Camelia Sinensis Kuntz.)
